Net Safe Bearing Capacity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Net Safe Bearing Capacity in Soil = Net Ultimate Bearing Capacity/Factor of Safety in Bearing Capacity of Soil
q_nsa = q_net'/FOS
This formula uses 3 Variables

Variables Used

Net Safe Bearing Capacity in Soil - (Measured in Pascal) - Net Safe Bearing Capacity in Soil is the net ultimate bearing capacity divided by factor of safety.
Net Ultimate Bearing Capacity - (Measured in Pascal) - Net Ultimate Bearing Capacity is the maximum load per unit area that a soil can withstand without failure under the conditions imposed by the presence of groundwater.
Factor of Safety in Bearing Capacity of Soil - Factor of Safety in Bearing Capacity of Soil expresses how much stronger a soil is than it needs to be for an intended load.

STEP 1: Convert Input(s) to Base Unit

Net Ultimate Bearing Capacity: 5.3 Kilonewton per Square Meter --> 5300 Pascal (Check conversion here)
Factor of Safety in Bearing Capacity of Soil: 2.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

q_nsa = q_net'/FOS --> 5300/2.8

Evaluating ... ...

q_nsa = 1892.85714285714

STEP 3: Convert Result to Output's Unit

1892.85714285714 Pascal -->1.89285714285714 Kilonewton per Square Meter (Check conversion here)

FINAL ANSWER

1.89285714285714 ≈ 1.892857 Kilonewton per Square Meter <-- Net Safe Bearing Capacity in Soil

< Bearing Capacity of Soils Calculators

Ultimate Bearing Capacity of Soil under Long Footing at Surface of Soil

Go Ultimate Bearing Capacity = ((Prandtls Cohesion/tan(Angle of Internal Friction of Soil))+(0.5*Dry Unit Weight of Soil*Width of Footing*sqrt(Coefficient of Passive Pressure))*(Coefficient of Passive Pressure*exp(pi*tan(Angle of Internal Friction of Soil))-1))

Net Ultimate Bearing Capacity given Ultimate Bearing Capacity

Go Net Ultimate Bearing Capacity of Soil = Ultimate Bearing Capacity-Effective Surcharge in Kilo Pascal

Ultimate Bearing Capacity

Go Ultimate Bearing Capacity = Net Ultimate Bearing Capacity of Soil+Effective Surcharge in Kilo Pascal

Effective Surcharge given Depth of Footing

Go Effective Surcharge in Kilo Pascal = Unit Weight of Soil*Depth of Footing

Net Safe Bearing Capacity Formula

Net Safe Bearing Capacity in Soil = Net Ultimate Bearing Capacity/Factor of Safety in Bearing Capacity of Soil
q_nsa = q_net'/FOS

What is Bearing Capacity?

In geotechnical engineering, bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil.

How to Calculate Net Safe Bearing Capacity?

Net Safe Bearing Capacity calculator uses Net Safe Bearing Capacity in Soil = Net Ultimate Bearing Capacity/Factor of Safety in Bearing Capacity of Soil to calculate the Net Safe Bearing Capacity in Soil, The Net Safe Bearing Capacity formula is defined as the maximum allowable pressure or load that can be applied to the soil or rock beneath a structure without risking shear failure or excessive settlement. Net Safe Bearing Capacity in Soil is denoted by q_nsa symbol.

How to calculate Net Safe Bearing Capacity using this online calculator? To use this online calculator for Net Safe Bearing Capacity, enter Net Ultimate Bearing Capacity (q_net') & Factor of Safety in Bearing Capacity of Soil (FOS) and hit the calculate button. Here is how the Net Safe Bearing Capacity calculation can be explained with given input values -> 0.013679 = 5300/2.8.
